The applicaion of curve fitting technique in fabric defect detection

To fabric defect detection of rapidity and accuracy, a new method for defect detection based on curve fitting is presented. Firstly, acquiring fabric images are processed with median filter. Then take the measures of curve fitting to the enhanced defect imagines. Finally, the edge detection was carried out to the fabric defect. Experimental results show that the algorithm can effectively suppress noise, the edges are clear and accurate, that this method improves the speed of the defect detection while keeping the accuracy of the defect detection.
